NOVELTY - A composite anti-wear agent comprises hydroxy silicone oil, PTFE micropowder, BYK additive and graphene oxide. USE - The composite anti-wear agent is useful in a polyurea elastomer coating (claimed). ADVANTAGE - The composite anti-wear agent has excellent mechanical property and bonding force and reduced friction coefficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a wear-resistant polyurea elastomer coating, which comprises a component (A) containing polyether glycol, diisocyanate and diluent, and a component (B) containing amino-terminated polyether, amino chain extender, anti-wear additive and catalyst, where the anti-wear additive comprises the composite anti-wear agent.
